Let's divide 868640 by 78
Let's see how many times 78 fits into 868640.

Going ahead to step 1:
8 divided by 78 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 78

Moving on to step 2:
The number 78 fits into 86 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 78 from 86 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 78

Advancing to step 3:
78 can be fit into 88 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 78 from 88 leaves us with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 78

Step 4:
If we divide 106 by 78, we get 1 and a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 111.0
The remainder is 28 after subtracting 78 from 106.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 78

On to step 5:
78 goes into 284 3 times with a remainder of 50.
The next digit of our result is 3. 
Result so far: 1113.0
Deduct 234 from 284 and we're left with 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 78

Advancing to step 6:
If we divide 500 by 78, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 11136.0
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
If we divide 320 by 78, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 11136.4
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
The number 78 fits into 80 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 11136.41
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
20 divided by 78 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11136.41
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 11136.4102
Deduct 156 from 200 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
When dividing 440 by 78, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 11136.41025
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 11136.410256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
When dividing 320 by 78, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11136.4102564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
80 divided by 78 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11136.41025641
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 11136.41025641 and a remainder of 2e-09.
